both my 2019 3.5 and my 2023 powerboost with less than 800 miles has done this since new when running at idle. I'm sure it's just a characteristic of the engine.
I know when it snowed here in central Texas a few years ago I had no problems in the snow. Of course I took the opportunity to take it out and throw it into 2wd and play around with it then threw it in 4wd and had no problems getting around.
I installed the tow mirrors I bought and programmed them in with forscan and had to do a 360 camera calibration. I got them for just over $1400 shipped brand new.
